string size / lenght problem

[capeone]

Hello,
i have problem with size() function.
Whenever i want to count how many characters have string i typed from console, i got wrong value.
The problem is that size() counts characters to first space in typed string.

in code
string strNps ="Bla bla bla"
int i = strNps.size()
integer i gets correct value (11)

but in code
string strNps;
cin>>strNps;
int i = strNps.size();
integer i gets number of characters to first space - for example for typing "Bla bla bla" int i gets value 3.

How to solve it?

cin >> ... will only get the the text upto the first space, try getline

No, it doesn't, as the first lines of your snippet demonstrate. Your problem is the >> operator. It uses whitespace as a delimiter, so cin >> strNps; reads input until it finds a whitespace and leaves the rest of the input in the stream. You want to use getline():

string s;
getline(cin, s)
cout << s.size() << endl;

EDIT: too slow...
